FlLL-AND-DRAINAGE VALVE FOR TANKS.

SPECIFICATION forming part of Letters Patent No. 550,064, dated November19, 1895. Application filed April 23, 1894. Renewed A ril 29, 1895-Serial No. 547,574. (No model.)

To aZZ whom it may concern:

Be it known that I, ARCHIBALD B. WILSON, a citizen of the United States,residing at Chicago, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Fill-and-Drainage Valvesfor Tanks, which are fully set forth in the following specification,reference being had to the accompanying drawings, forming a partthereof.

This invention relates, primarily, to tanks which are supplied by a pumpoperated by a windmill or other source of power above the tank, thepump-barrel extending up into the tank and constituting the supply-pipe,and the pump-rod extending down through such supply-pipe or pump-barrelfrom the source of power above to the source of water below the tank.The device, however, is not strictly limited to use in just suchsituations, but may be employed whenever a tank is kept supplied by apipe which protrudes up through the bottom, and its immediate purpose isto permit the tank to be emptied back to the source of the supply pastthe same valve through which it is supplied, and also to make itpossible to repair or remove the pump without draining the tank and torelieve the pump-valve of the labor of holding the tank full when thepump is not in operation.

In the drawings, Figure 1 is a sectional elevation of a tank and aportion of the supporting-tower, the tank-wall being partly broken awayto show the supply-pipe, pump rod and valve, and connections therein.Fig. 2 is a vertical section through the middle of the valve-fittingwhich pertains to my invention.

The tank C has the fitting F, secured to the inner surface at the centerof the bottom of the tank. This fitting has the chamber F and the hollowbosses F and F projecting, respectively, upwardly and downwardly andinteriorly threaded. The lower section D of the pipe is screwed into thelower boss and the upper section D into the upper boss. The upper wallof the fitting has an opening F closed by a valve G, pivoted to the lugsf f, which project from the upper surface of said upper wall. This valveterminates at its outer edge in an eye G, with which a hook II isengaged, said hook being fastened to the lower end of a cable H, whichis connected at the upper end to the inner end of the lever J, which isfulcrurned upon the upper edge of the tank and has attached to its outerarm a cable K, extending down outside the tank and tower to a convenientpoint for operating the same to lift the valve.

It will be understood that when the pump is in operation the inflow ofthe water will lift the valve.

When for any purpose it is desired to completely empty the tank, theoperator will pull down the cable K, and thereby lift the valve, and byfastening the cable cause it to remain open until the tank is drained.

When it becomes necessary to remove or repair the pump, it can be donewithout disturbing the contents of the tank, and even the lower sectionD of the supply-pipe can be detached without draining the tank, and atall times the pipe D, extending up into the tank as high as the latteris to be filled, prevents the water from leaking back through the pumpwhen the latter is not in action, as might happen if the valves wereloosely fitted. The presence of the pipe therefore renders itunnecessary to maintain the pump-valves so tightly fitted as wouldotherwise be necessary, and thus permits them to be relieved of thewater-pressure while the pump stands idle.

I claim- 1. In combination with the tank and the pump barrel or supplypipe extending up through the bottom of the tank and open at a distanceabove the bottom and having the pump rod extending through it, such pipehaving the discharge port into the tank at the bottom thereof, and avalve for such port adapted to be opened inwardly with respect to thetank by the inflow of the water, and to be normally seated and providedwith connections extending outside the tank to open it at will:substantially as set forth.

2. In combination with the tank and the pumpbarrel or supply pipeextending up through the bottom of the tank and open at a distance abovethe bottom and having the pump rod extending through it, such pipecomprising the inlet and drainage fitting F, secured to the innersurface of the bottom of the tank, and constituting a coupling betweenthe pipe sections D and D, which extend re spectively above and belowsaid fitting, the fitting having a discharge opening in its upper walland a valve seating downwardly to close the same; and connections fromsuch valve outside the fitting extending outside the tank to open thevalve at will: substantially as set forth.

In testimony whereof I have hereunto set my hand, in the presence of twoWitnesses, at Chicago, Illinois, this 16th day of April, 1804. 10
